info | The info. |

Note: Cannot be called from an

Adds a virtual child which is a descendant of the given root
.
If virtualDescendantId
is NO_ID
the root
is added as a child.
A virtual descendant is an imaginary View that is reported as a part of the view hierarchy for accessibility purposes. This enables custom views that draw complex content to report them selves as a tree of virtual views, thus conveying their logical structure.
root | The root of the virtual subtree. |
---|---|
virtualDescendantId | The id of the virtual child. |
Compares this instance with the specified object and indicates if they
are equal. In order to be equal, o
must represent the same object
as this instance using a class-specific comparison. The general contract
is that this comparison should be reflexive, symmetric, and transitive.
Also, no object reference other than null is equal to null.
The default implementation returns true
only if this ==
o
. See Writing a correct
equals
method
if you intend implementing your own equals
method.
The general contract for the equals
and hashCode()
methods is that if equals
returns true
for
any two objects, then hashCode()
must return the same value for
these objects. This means that subclasses of Object
usually
override either both methods or neither of them.
obj | the object to compare this instance with. |
---|
true
if the specified object is equal to this Object
; false
otherwise.Finds AccessibilityNodeInfo
s by text. The match
is case insensitive containment. The search is relative to this info i.e. this
info is the root of the traversed tree.
Note: It is a client responsibility to recycle the
received info by calling recycle()
to avoid creating of multiple instances.
text | The searched text. |
---|
Find the view that has the specified focus type. The search starts from the view represented by this node info.
focus | The focus to find. One of FOCUS_INPUT or
FOCUS_ACCESSIBILITY . |
---|
Searches for the nearest view in the specified direction that can take input focus.
direction | The direction. Can be one of:
FOCUS_DOWN ,
FOCUS_UP ,
FOCUS_LEFT ,

FOCUS_BACKWARD . |
---|
Gets the actions that can be performed on the node.
Gets the node bounds in parent coordinates.
outBounds | The output node bounds. |
---|
Gets the node bounds in screen coordinates.
outBounds | The output node bounds. |
---|
Get the child at given index.
Note: It is a client responsibility to recycle the
received info by calling recycle()
to
avoid creating of multiple instances.
index | The child index. |
---|
IllegalStateException | If called outside of an AccessibilityService. |
---|
Gets the number of children.
Gets the collection info if the node is a collection. A collection child is always a collection item.
Gets the collection item info if the node is a collection item. A collection item is always a child of a collection.
Gets the content description of this node.
Gets the node's live region mode.
A live region is a node that contains information that is important for
the user and when it changes the user should be notified. For example,
in a login screen with a TextView that displays an "incorrect password"
notification, that view should be marked as a live region with mode
ACCESSIBILITY_LIVE_REGION_POLITE
.
It is the responsibility of the accessibility service to monitor
TYPE_WINDOW_CONTENT_CHANGED
events
indicating changes to live region nodes and their children.
ACCESSIBILITY_LIVE_REGION_NONE
if the view is
not a live region.Gets the movement granularities for traversing the text of this node.
Gets the package this node comes from.
Gets the parent.
Note: It is a client responsibility to recycle the
received info by calling recycle()
to avoid creating of multiple instances.
Gets the range info if this node is a range.
Gets the fully qualified resource name of the source view's id.
Note: The primary usage of this API is for UI test automation
and in order to report the source view id of an AccessibilityNodeInfoCompat
the client has to set the FLAG_REPORT_VIEW_IDS
flag when configuring his AccessibilityService
.
Gets the id of the window from which the info comes from.
Returns an integer hash code for this object. By contract, any two
objects for which equals(Object)
returns true
must return
the same hash code value. This means that subclasses of Object
usually override both methods or neither method.
Note that hash values must not change over time unless information used in equals comparisons also changes.
See Writing a correct
hashCode
method
if you intend implementing your own hashCode
method.
